Product Details

Dayton Audio PT2C-8 Planar Tweeter

Many audiophiles praise the Dayton Audio PT2C-8 ribbon tweeter's excellent clarity, transparency, and imaging. The key to this remarkable performance is the almost weightless ribbon element: a Kapton film membrane etched with a pattern of aluminum conductors and placed precisely between two rows of neodymium magnets. The result is an immediate response to any transient impulse found in the original signal.

The Dayton Audio PT2's ability to deliver musical detail is clearly amazing. The tweeter's large membrane and radiating area provide higher power handling and a substantially lower cut off frequency. This membrane is thermally attached to a cast aluminum plate that facilitates cooling and dramatically increases dynamic range. The flared waveguide's wide horizontal dispersion projects an excellent off axis response. At the same time, vertical dispersion is limited, which reduces distracting floor and ceiling reflections. Perfect for line array applications. The recommended second order crossover cut-off frequency is 3 kHz or higher, although the crossover point can be lowered to 2,500 Hz if a 3rd order crossover is used.

Dayton Audio PT2C-8 Planar Tweeter is rated 4.6944 out of 5 by 36.
Rated 5 out of 5 by from well builtI got these Dayton planners, Dayton 2" mid domes, Dayton 8" designer series speakers, and the100 watt Dayton 3-way crossover for my first DIY project . When I received the order ,I though wow!! These are some well built speakers . I build a .8 cu FT with a 2.5" port 1 " . Installed these speakers, an the x-over . Running them off a 80 watt rms x 5 pioneer VSX-822 the speakers were a little rough sounding at first , but after I reversed the polarity on the mid an added an l-pad on the mid to turn it down a little bit , these tweeters really sound awesome. very crisp but not harsh at all . really clear sounding and can be cranked up LOUD an still sound great. They sound best at ear level .This project with all the Dayton products work great together an sound awesome .So if you r planning a project ,you wont be disappointed with Dayton products, or the prices.

Rated 5 out of 5 by from Clean reproductionI bought it to use it as a linesource to compliment my ESS Heil AMT mid/tweeters. Blends well on a linesource configuration with other ribbon drivers. It has similarities to carver sunfire loudspeaker ribbons used on their smaller speaker designs. You need to match this with quality crossovers in order to produce it's maximum efficiency. For the price, it is a bargain and highly recommended for small to large linesource DIY loudspeaker projects. Well designed as a replacement as well. This is much more quality design compared to other similar designs. Highly recommended!

Rated 5 out of 5 by from Excellent - Better than dome tweetersI've Infinity Primus 360 and came across a review by Stereophile magazine which showed a sudden steep dip in response curve at around 16 KHz. I wanted to replace them for a long time. Recently listened to Martin Logan Motion 40 with planar tweeters and I was really impressed. They are around a grand each though so took a poor man's route and bought a pair of these to replace the factory tweeters. However, after ordering, I found that the factory tweeters are only 4 ohms and replacing them with 8 ohm ones would shift the crossover point leading to other issues. But I wanted to listen to these quickly so ordered a few capacitors and inductors the very next day. I'm currently using these on the high side of a 2-way first order Butterworth crossover at 10KHz and the entire Primus on the low side. I guess this is not ideal [Primus has a 3-way fourth order crossover] but the sound is already superb. If I had to describe - it is soft but clear, loud but not harsh.Any suggestions for the crossover?

Rated 5 out of 5 by from Excellent Kick Panel TweeterI have a pair of these installed in a Mazda MX-5 Kick panel. They are amazing value when installed properly.

Rated 5 out of 5 by from Smooth and ClearThis is my first time building a speaker and I knew I wanted Planar Tweeters. I am glad I bought these, they are really clear and smooth sounding and handle power very well. When I opened the box I had no idea they were this large. I could not be happier with my purchase, these are great!

Dayton Audio PT2C-8 Planar Tweeter

Which speaker lug is the positive, the large one or small one?

Asked by: cincylion
The Dayton Audio PT2C-8 Planar Tweeter is a non polar ribbon type tweeter and as such has a characteristic that doesn't require phasing or polarity considerations. Unlike a cone speaker that pushes out sound in a forward movement, this speaker yields sound in both forward and reverse directions. It's movement is more of a twerping rather than a movement. Either terminal connection should be OK. If you like, try both to see if you discern a difference in sound output.God Luck

can this be used for car audio?

Asked by: davidrader65
I have a pair of these installed in my 08 Mazda MX-5 kick panels. A pair of Aura NS-6 are installed in the factory door locations. If these were retailed as a Car Audio set the price would be astronomical. I am very pleased with the Performance.

If a 4th-order crossover (24 dB/oct) is used, can the crossover point be dropped to 2kHz?

If it can be used with that crossover frequency, does the power rating get reduced?
Asked by: Scott S
2kHz would be pushing the boundaries a bit, even at 24dB/octave. I'd hate to tell you to try it, and then have something bad happen to your planar tweeter. I'd be more comfortable trying it at 2.5kHz personally. Others may have different advice. And yes, power handling typically increases and decreases proportional to the crossover point, at least to some extent.

What bypass capacitor should be used in series to allow only 3.5k hz and up to enter this Planar? .

These tweeters are "independent", with their own full-range source from the "A" speaker" amplifier output rated at 70w per stereo channel, per side; therefore, 280 total watts. The "B" speaker amplifier output is connected to a pair of 295-605 mid-woofers in another cabinet. Both "A" and "B" carry 8-16 ohm ratings.
Asked by: Kilty
If you want to cross this tweeter at 3.5kHz I would recommend at least a second order filter. If you use only a cap it will have to be crossed around 7kHz in order to be properly protected. I would recommend a 4 uF cap and 0.5 mH inductor for a crossover point of 3.5kHz.

The sticker on the back of this driver says 80W max. The specs claim 80W rms, 115W max. Which is correct?

Asked by: scinos
The silver sticker that was on the older versions of this tweeter were in error. With a 2nd order crossover at 3000Hz or higher, the power handling is 80w RMS, 115w max on this tweeter. I apologize for any confusion.

Compatible mid range

With a spl of 94db would the Dayton RS52AN-8 dome mid range at a possible spl of 91db be compatible?
Asked by: cavemanmusic
If you are insistent on using a midrange, the Dayton would work. You might need an L-pad on the ribbon transducer to match levels. However, this ribbon has good enough upper midrange response that if you use a woofer with good lower midrange, you will not need a dedicated mid.Most of the small (under 6") woofers do have good response to 2500 Hz or so.In practice it seems much easier to get excellent results using a simpler 2 way midwoofer/tweeter design supplemented with a powered subwoofer. This seems to be the way the engineering is headed these days. Both the Dayton ribbon mid/tweeter cited here and the BG planars represent, IMHO, a major step forward in speaker system design. These offer quality similar to electrostatics without all the nasty side phenomena known to those of us dinosaurs who lived through the electrostatic planar speaker era.
